You've got come pretty obvious things in your bloodwork to fix
Fix them
Your SHBG is high, which can cause symptoms of low test.
Stop the low carb BS to fix that and try boron
Your body doesn't have a receptor to tell if food is processed or not. This does not matter. Only the macros matter.
If anything, calorie dense processed foods are what your skinny ass needs right now.
You have high cholesterol. Replace your beef with chicken or other low fat meat. Get rid of any saturated fats in your diet. Start taking an omega fatty acid supplement. You need healthy fats, not beef fats.
Your bodyweight says you aren't eating, and your cholesterol says the food you are eating is the wrong food.
These are easy fixes my dude. Eat more, eat CORRECTLY, train hard, and sleep.
